20inch wheels question

alpine92m3 · 04-30-2011, 01:34 PM

Do 20 inch wheels slow down your car much? Performance, ride , handling? Any body with any experience with 20s ? Any regrets do's and dont's?

20" wheels can have a significant effect on the performance of the vehicle. Slows you down a bit(wheel weight and circumference increase). Also, I know ride quality suffers and I've HEARD that the cars handling gets compromised(not sure about that tho). I asked for an explanation from the gentleman but he never got back to me. I wasn't doubting the guy but based on my knowledge and the fact that there are many high performance vehicles that come with stock 20's, I didn't really understand how handling gets compromised when rolling on DUBS. Car looks sooper sick tho!!! Hope this helps.

20's will not result in a circumference increase if you buy the correct tires. When you get 20's you reduce the profile on your tires which results in the same overall diameter vs. 18's or 19's. If you buy a heavy 20" wheel then it will slow you down but there are 20" wheels available that weigh less than or equal to many 19" wheels. In fact it's relatively easy to find quality 20" wheels lighter than the OEM 19" ZCP wheels. I previously had 20" volk G2's that weighed +/- 24 lbs in 20 x 11". The primary disadvantage of 20" wheels is ride quality and less durability. Lower profile tires result in less rubber between you and the road which means more road feel / less shock absorption. The other disadvantage is that most 20" wheels and tires are more expensive than comparable 19" or 18". If you get 20's be sure to buy something light-weight and forged in order to minimize the performance disadvantages. I would stick with Volk, BBS, Advan, and HRE.

Hope this helps!

Hey chris s .. What have you heard about forgestar . anything good?

alpine92m3 · 04-30-2011, 07:42 PM

What about forgestar wheels??

Crazy Bimmer · 04-30-2011, 07:47 PM

They not forged. I would say they are comparable to VMR.

chris s · 04-30-2011, 08:14 PM

Not a light wheel as far as I know...and as mentioned, not forged. I don't have any first hand experience with them myself. Comparable to a VMR sounds about right.

alpine92m3 · 04-30-2011, 08:14 PM

Ok ok thanks alot for the information guys .. I was lied too about forgestar being forged then... Mhmmm

I stand corrected. Sorry, I just went through figuring out which tires I should get for myself and circumference was slightly increased in MY case. But yea, he's right. Depends on what size tires you get...
